Adobe Systems Inc. on Tuesday released security updates to remedy at least 13 security flaws in its PDF Reader and Acrobat software. Updates are available for Mac and Windows versions of both programs. Last month, Adobe said it would begin rolling out security updates every three months, and yesterday was the first installment under that program, which is timed to coincide with Microsoft’s Patch Tuesday in a bid to lighten the load on businesses that have to test these patches before deploying them. The latest update brings both Reader and Acrobat to version 9.1.2. Users can grab the latest versions via the updater built-in to the programs (from the menu, click “Help,” then “Check for Updates”) or from the links in the accompanying security advisory for this rollup.. Adobe said security updates for Adobe Reader on the UNIX platform will be available on June 16, 2009.
